Researchers find hepatitis A and hepatitis C attack same protein to block immune defenses

CSHL research ties harmless viruses to cancer

...the successes of preventative immunization against hepatitis B and papilloma viruses, which both cause cancer. Lazebnik and his CSHL colleague Dominik Duelli estimate that at least 18 of 29 virus families that infect human cells have species that fuse cells, which implies that CIN and cancer might be caused by...

New culture method for hepatitis C virus uses primary hepatocytes and patient serum

Researchers open the way for improved study of hepatitis C virus by devising a novel virus culture system that allows replication of patient-isolated virus in nontransformed hepatocytes, instead of culture-adapted virus strains in transformed cell lines. The related report by Lázaro et al, "Hepatitis C vi...

New UD technology removes viruses from drinking water

...against human pathogens including E. coli 0157:H7, hepatitis A, norovirus and rotavirus. Rotavirus is the number-one cause of diarrhea in children, according to Kniel. "In 20 minutes, we found 99.99 percent removal of the viruses," Chiu said. "And we found that removal of the viruses got even better than th...
